It is either inserted or planted at the same time as the core material is formed at the time of manufacturing the composite board, but there is a disadvantage that the position is displaced due to the band. Also, the composite plate was significantly lighter than before, but was considerably heavier than the core material made of plastic foam alone.

It is possible to block gaps and the like in the connecting portion, absorb dimensional errors, and significantly improve heat insulation, airtightness, and workability. Since the guides for the front and back surface materials can be reliably made of non-combustible plate material during manufacturing, it can be manufactured with high accuracy, and the mechanical strength of the connecting part,
Engaging force can be significantly strengthened. By forming the packing material, the fireproof and waterproof properties of the joint can be greatly improved. Male,
It is extremely easy to fit the female type connecting portion. There are characteristics and effects.

A core material, which is mainly composed of a plastic foam having a fireproofing performance of a semi-incombustible material or more, is integrally formed between a surface material and a back surface material made of a long plate material on a body, and the In a joint structure in which a composite plate having male and female connecting portions on both sides is connected, the male connecting portion is a side surface formed in parallel in the order of a guide ridge, a fitting groove, a ridge and a housing groove, and the fitting. A non-combustible plate material is integrally inserted in the center of the insertion groove so as to be embedded in the core material from the surface of the insertion insertion groove, and a female connection by lowering the end of the male connection portion from the decorative surface of the surface material. The female connecting portion includes a joint stepped surface cover portion, a concave line for inserting the guide convex line, and a main convex line and the convex line that fit into the fitting insertion groove. The sub-relief ridge to be fitted and the sub-relief ridge corresponding to the storage groove are configured in parallel with the side face in this order, and at the center of the main ridge. A non-combustible plate material is planted integrally with the core material, and when the male connecting portion and the female connecting portion are fitted together, at least the space between the fitting groove and the main ridge is fireproof, waterproof and cushioning. A joint structure characterized in that a certain packing material is interposed and the packing material and the non-combustible plate material interposed in each of the connecting portions are in contact with each other.
